Analyzed flocks information.

Note that the observation duration is a video time length. Because of an angle view limitation, time length of some individuals is shorter than the observation duration. Pearson’s r and N are the correlation coefficient of vs. in Fig. 6(a) and the analyzed pair number of each flock, respectively. Pearson’s P of each flock is less than . Note that possible number of independent data is because . N is, however, smaller than it in some groups because there are some pairs which do not appear in the same frame.whose time series are not enough to calculate .
